Tube and method of forming the same

My invention may be advantageously employed in the manufacture of fancy tubes adapted for forming casings of fountain pens, pencils, umbrella handles, etc., from sheet celluloid, cellulose nitrate, cellulose acetate, other productsof cellulose, or any suitable substance which may be formed into a tube by rolling a primarily plain sheet moistened with a solvent of such substance which 10 causes the contiguous convolutions to cohere;

The present cost of plain celluloid is about forty cents per sheet (.010 X X 50") but celluloid including metallic powders forming clouded effects therein, costs ninety cents per 155' sheet, and what is known as pearl celluloid, viz., clear celluloid in which fish scale powder is suspended and which has the appearance of mother of pearl, costs $2.50 per sheet;

Altho it is highly advantageous to use as little as possible of such costly fancy ma terials in such tubes; they have heretofore been made entirely of the costly materials. The essential feature of my invention is such construction, arrangement and disposition of a minimum quantity of the costly material in a tube formedprincipally of cheaper material, as to convey the impression that the entire tube is formed of such costly material. As hereinafter described, such minimum quantity of such fancy material may be in the form of an extremely thin sheet, which I term a pattern piece, of such extent as to form but a single convolution in the tube, and such pattern piece may be covered and its beauty light is refracted and reflected, and, if such pattern piece be translucent, it may be backed by opaque material concealing the contents of the tube such as ink in a fountain pen or i the metal or the wooden stick of an umbrella or cane.

vMy invention includes the various novel enhanced, by transparent material in which sheet of-material with a pattern piecethereon, forming a tubeblank. Fig. III is an edge view similar toFig. II

Fig. VI is a fragmentary vertical sectional View of die meansv for punching'the pattern and filling pieces shown infFigs. IV and J Referring to' the inner tube 1 may be formed of cheap material in conven ient way,for instance, by boring a solid rod of celluloid or the like, orbyxextrusion in primarily tubular form, or by rollinga thin sheet of the desired material'while moistened with a suitable solvent. Acetone is a suitable solvent for celluloid and cellulose nitrate but I prefer to employ ethyl acetate or a mixture of alcohol and ether 'as a solvent for cellulose acetate. The latter is preferable t0} termed a patternpiece. 5 Said pattern piece t-may be entirely covered by the outer tube like;

v 5 which may be transparent celluloid or the Sucha tube as-shown in Fig- I may be formed by rolling the primarily plane sheet shown in Fig. II which may be formed of celluloid or the like .010 of an inch thick, and

of which the portion-from 6 to 7' may be opaque white and the portion from 7 to 8 may be clear. The pattern piece 10 may be a'primarily plane sheet of celluloid or the like, offancy appearance, forin'stance, what is known to the trade as mottled blue, i.'e., a mixture of different shades or tints of translucent blue celluloid, Such a blank 3S in icated in Fig, II may be Inoistened with a solvent andv rolled to form such atube as shown in Fig. -I,lwherein the fancy strata 4 is fo'rnied'by the pattern'piece between the opaque inner tube 1 formed by the convolutions of said sheet from .6 to and the translucent tube 5 is formed bythe portion s In Fig. III, the tube blank" sheet m be inclosed between the convolutions of said sheet; thepattern piece forming a complete convolution visible throughout the entire circumference of'the tube; the portion of said sheet extending outwardly from said pattern piece beingtranslucent, so that said pattern piece is visible therethrough; whereby "the pattern of said piece is manifested throughout the entiresuperficial area of said tube.
